Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please refer to Figures 1 to 9This utility model provides a mandrel storage tool rack, including a frame body 01. A first fixing frame 11 is provided at the lower part of the frame body 01, and a first storage part 02 is installed on the first fixing frame 11. The first storage part 02 is for placing long-axis tapered mandrels. A second fixing frame 12 is provided in the middle of the frame body 01. A guide square tube 03 is horizontally installed on the second fixing frame 12 along the short axis of the frame body 01. A second storage part 04 is slidably installed on the guide square tube 03, so that the second storage part 04 can move back and forth along the guide square tube 03. The second storage part 04 is specifically for placing small and medium-sized fixed mandrels and plastic mandrels.

[0033] In one embodiment, a lower guide wheel 31 with its axis perpendicular to the side of the guide square tube 03 is rotatably mounted on the lower side of the guide square tube 03 facing the outer end of the frame 01. Correspondingly, an elongated hole is opened on the bottom surface of the end of the guide square tube 03, and the outer circular surface of the lower guide wheel 31 can extend into the interior of the guide square tube 03 along the elongated hole.

[0034] Among them, a side guide wheel 32 with its axis perpendicular to the top of the guide square tube 03 is rotatably installed on the side of the guide square tube 03 facing the outer end of the frame 01. Correspondingly, an elongated hole is opened on the side of the end of the guide square tube 03, and the outer circular surface of the side guide wheel 32 can extend into the interior of the guide square tube 03 along the elongated hole.

[0035] In one embodiment, the second storage section 04 includes a push rod 41, a support block 42, and a tray 43. One end of the push rod 41 is slidably mounted inside the guide square tube 03 along the lower guide wheel 31 and the side guide wheel 32, while the other end of the push rod 41 is externally positioned outside the guide square tube 03 and connected to the support block 42. The tray 43 is mounted on the support block 42 and has a holding hole 44. When the push rod 41 moves along the guide square tube 03 to the outside of the frame 01, the tray 43 can be pulled out of the frame 01. When placing the mandrel, the surface of the tray 43 contacts the non-use surface of the mandrel, and one end of the non-use surface of the mandrel is sunk into the holding hole 44 to achieve the purpose of fixing the mandrel and effectively prevent bumps and scratches during the use of the tooling.

[0036] Among them, the push rod 41 is rotatably mounted with a first guide wheel 45 whose axis is perpendicular to the top of the guide square tube 03 at the end away from the support block 42. The outer circular surface of the first guide wheel 45 extends from both sides of the push rod 41, and the outer circular surface of the first guide wheel 45 is tangent to the inner wall of the guide square tube 03.

[0037] Among them, the end of the push rod 41 away from the support block 42 is rotatably mounted with a second guide wheel 46 whose axis is perpendicular to the side of the guide square tube 03, and the outer circular surface of the second guide wheel 46 is tangent to the inner wall of the guide square tube 03.

[0038] Among them, the end of the guide square tube 03 facing the outside of the frame 01 is higher than the end of the guide square tube 03 facing the middle of the frame 01, so that the guide square tube 03 is set at an angle; when the mandrel is removed, the push rod 41 can automatically return to its original position along the guide square tube 03 due to the influence of the gravity of the second storage part 04.

[0039] The top of the first storage section 02 is provided with continuously distributed V-shaped positioning grooves 21. The first storage section 02 is made of wood or a material with low hardness to avoid bumps and scratches during the contact between the mandrel and the tooling frame.

[0040] In one embodiment, a support plate 05 is horizontally fixedly installed on the top of the frame 01. The support plate 05 has a receiving hole 51, which can accommodate a large fixed mandrel and a plastic mandrel.

[0041] Rubber pads 06 are provided on the upper surfaces of the tray 43, the first storage section 02, and the support plate 05 to effectively prevent bumps and scratches on the spindle surface.

[0042] In one embodiment, the guide square tubes 03 can be arranged in two sets, and the two sets of guide square tubes 03 are in opposite directions, which enables the push rod 41 to be pulled outward along both sides of the frame 01, so that the second storage part 04 can be flexibly retracted on both sides of the frame 01, which can effectively save placement space.

[0043] When in use, long-axis tapered mandrels can be placed on the first storage section 02, while large fixed mandrels and plastic mandrels can be placed on the support plate 05; and small and medium-sized fixed mandrels and plastic mandrels can be placed on the tray 43, thereby achieving multi-layered placement and management of the top, middle and bottom layers according to the size and type of the mandrel.

[0044] The intermediate layer is specifically designed for placing small and medium-sized fixed mandrels and plastic mandrels: Before placing the mandrel, the push rod 41 can be pulled out along the guide square tube 03. At this time, the lower guide wheel 31 and the side guide wheel 32 will form rolling support for the push rod 41 in the lateral and longitudinal directions at the end of the guide square tube 03, so as to guide and limit the push rod 41 and ensure that the push rod 41 slides out. The first guide wheel 45 and the second guide wheel 46 at the end of the push rod 41 can make the push rod 41 form rolling support in the lateral and longitudinal directions on the inner wall of the guide square tube 03, and cooperate with the lower guide wheel 31 and the side guide wheel 32 to achieve four-point support guidance for the push rod 41. When placing the mandrel, the tray 43 surface contacts the non-use surface of the mandrel, and the non-use end of the mandrel is sunk into the holding hole 44 to achieve the purpose of fixing the mandrel. Then, under the action of gravity of the mandrel and the second storage part 04, the push rod 41 will automatically return to its position.

[0045] When retrieving the mandrel, the push rod 41 can be fully pulled out along the guide tube 03. Due to the weight of the mandrel and the angle created by the inclined arrangement of the guide tube 03, the second guide wheel 46 at the end of the push rod 41 exerts greater pressure on the top of the guide tube 03, while the bottom of the push rod 41 presses down on the lower guide wheel 31. The second guide wheel 46 and the lower guide wheel 31 exert opposing forces on the end of the push rod 41, maintaining a balanced force on the end of the push rod 41. The first guide wheel 45 and the side guide wheel 32 provide a lateral limit, which, combined with the longitudinal limit formed by the second guide wheel 46 and the lower guide wheel 31, prevents the push rod 41 from sliding out of the guide tube 03. After removing the mandrel, the inclined guide tube 03 will cause the push rod 41 to automatically return to its original position.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
